NIMAS (National Instructional Materials Accessibility Standard)
NIMAS files are the national standard for accessible k12 textbooks, and can be opened and read "as is" in Read:OutLoud. NIMAS files are the most versatile digital files, because they can be used to create many other file formats including PDF, ePub, and BRF. The NIMAS fileset consists of the following parts: an XML content file, an OPF package file, a PDF copy of the title page, ISBN, and copyright information, and a folder containing the full set of content images.

PDF (Portable Document Format)
Accessible PDF files contain hidden tags which provide navigation of text and graphics for screen readers.

ePub (Electronic Publication)
ePub files are designed for reflowable content, allowing the text display to be optimized for the preferences of the reader. This format can be used with e-readers or computer software. Calibre is an example of a computer software which can be used to open files with ePub extensions.

BRF (Braille Ready Format)
Braille-ready files contain a format which can be read by a braille refreshable display, or transmitted to a braille embosser to create a hard copy Braille book. This code allows people without sight to read electronic documents from computer disks or from the internet.

HTML (Hyper Text Markup Language)
HTML files contain a set of files with an index file that links all of the associated files together.

TXT/RTF (Text and Rich Text)
Text files are plain text versions of the file with no images associated, and no online navigation. The book may contain multiple chapters as separate text files.

DOC (Microsoft Word Document)
A DOC file is a Microsoft Word document which may or may not include images. When the document is formatted using styles, document properties, alternative text for images, and descriptions for charts and graphs, the document becomes accessible for the visually impaired.


About the Project

Our Mission:

Our mission is to assist Indiana’s local educational agencies meet their obligation under IDEIA 2004 to ensure that a free appropriate public education (FAPE) is available to children with disabilities and to enable them to participate in the general curriculum consistent with their Individual Educational Plan (IEP).

Project Overview:

In October 2006, the Indiana Department of Education, Department of Special Education, established a grant to fund the Indiana Center for Accessible Materials (ICAM) Project with the mandate to provide a state repository to coordinate with the National Instructional Materials Center (NIMAC) for obtaining accessible textbooks and core instructional materials, in the National Instructional Materials Accessibility Standard (NIMAS), for use by students with print disabilities. 

The NIMAC, in Louisville, Kentucky, will receive and catalog publishers' electronic files of print instructional materials in a standard format: the NIMAS. The center will provide these standardized files to those who have been authorized by states to obtain the files to produce textbooks and other core print instructional materials for blind, visually impaired and print disabled students.

The Central Indiana Education Service Center (CIESC) PATINS Project, has been appointed by the Indiana Department of Education, to serve as the oversight agency for the ICAM operations and as the authorized agency for coordinating with the NIMAC for the state and its local educational agencies.

ICAM services are available to Indiana educational agencies at no cost, and the staff will work to assist Indiana’s educational agencies in building their capacity to provide access to print instructional materials in specialized formats for the student who has been determined as having a print disability.

ICAM Services to Local Education Agencies:

  • Serve as a state repository for textbooks and core curriculum instructional material in specialized formats and tangibles for K – 12 students with qualifying print disabilities.
  • Provide requested accessible formats of textbooks and core curriculum instructional materials to local educational agencies in a timely manner.
  • Provide a tracking system.
  • Assure protection of copyrighted material.
  • Report data on ICAM requests filled from local educational agencies to the Indiana Accessible Materials Coordinating Council.
  • Provide training and technical assistance to local educational agencies on accessible technology tools and the use of accessible content in curriculum delivery.
